Identification and phylogenetic analysis of an okenone-containing halophilic purple sulfur bacterium;

To investigate the feasibility and the control condition of the conversion of sulfide to sulfur from man-made wastewater ,lab-scale downflow and upflow colorless sulfur bacteria(CSB) biofilm reactor packing with ceramsite was used.

A sulfur-zeolite fixed bed reactor was used to remove the nitrite, while autotrophic denitrify bacteria, sulfate reducing bacteria and colorless sulfur bacteria were used to remove nitrate in influent.

Compared with other methods,the sulfide removal process based on bio-oxidation with colourless sulfur bacteria is no catalyst,no chemical sludge to be disposed,low energy consumption,possible reuse of sulfur and fast process with high removal efficiency.

Packing with SRB ( Sulphate Reducing Bacteria ) for treating simulative wastewater with sulphate concentration and packing with CSB (Colourless Sulfur Bacteria) for treating s.

Purified purple non-sulfur bacteria 01S strain was separated and fostered from activated sludge of brewery wastewater and used to treat high concentrated organic brewery wastewater.

The primary researches on the amount distributions and groups of purple non-sulfur bacteria in estuary sludge of Xinyang Shihe river were carried out.

In order to improve the treatment efficiency of PSB, a strain of purple non-sulfur bacteria with high capacity of degradation was isolated and screened from nat.
